To ALL WHOM IT MAiconcnnnz.

Be it known that I, JA MESD. SiiITH,-'of tige -city, county, and. State of New York have invented it new and;

useful Improvement in Measuring-Faucets, oft which jthe following is'a. full, cleniynnd' exact description,'referenc'e beinghad to the eccompenying drawing, forming part of'thisspecifieation, and; in which- Figure 1 represents a side view'of a mea'suring-faucet constructed in ,ue'cordancewith my improvement, the

cover to the hieesuring-chaniber being" removed.

.Referring to the accompanying drawing, A represents thefcucetor main body thereof, having arranged between its spigot-end, at, end discharge-nozzle b, a cylindrical measuring-chamber, B, which is in eommuniea- 7 tion', by suitable openings in its vperiphery, ton opposite sides of'its a'xis, with the spigotportion a and noz zle b,- the latter of which, may be provided with o. gate, c, as usual. Within this measuring-chamber is a'rotary'drawl ng-end measuring-device, C, prefcrohly of the character; as represented in'the accompanying drawing, descrihed in Letters Patent of the United'states, N o.'70,242, issued to Moore and A1,]?- Emery, October 29,1867, and wherein'd is on inner revolving eccentric-cylinder, provided with radial'slid es, e, "arranged to clip it loose bolt, f, .th'zrt'is concentric to theouter cylinder or chamber B, so that on rotntin-g -a handle, G, that to the shaft g ofg the eccentric-cylinder d, the rad'ialrslides e operate to draw the fluid through the spigotportioh a 'of the foucet, and (the gatec heing o pened) deliver it through thenozzle b in ineasured quantities, rcorresponding to the capacities of the spaces formed hy the radial slides e and inner andouter cylinders 11 B,wherhy, on registering the number of rotations given te the eccentric-cylinder d, the total amountdischarged is'readily ascertainable, or the amount to be delivered fixed by the rotation ofthe handle any given distance or number of times, an indicator inhoth cases being used, in conneetion with the rotating-shaft g, to determine and regulate the same- In such an arrangement oi nieosuring fnu'cet, however; itfis highly important-not onlythdt the indicator operating in connection therewith ,should becapnhle of being readily set 0 1 adjnstedto register any desired quantity, with facilities for changing theposTtion of the dial-relativelyto the pointer, or vice vcrsa, as new or varied indications nrerequired 'to' be made, but also tliat the indicator should be capable of registering large its well essmall quantities without an objectionable multiplicity of gearconnecting the measuring-device with the indicators, I I v i v v Thefollowting combinations of devices serve to secure these endsine-prajcticeble end most eflicient man ner: Thug-secured to the one side of the measuring-chamber B, onits eirterior, by boss orprojeetion therefrom, in concentric relationshipto the shaft g, is a fixedicirculor-rz ck or wheel, I, eontz iining t given numberof teeth, while in the sh ne axial line, and lying in close proximity to said rack or wheel, is another aiid loose Orrotating wheel, J, ot' like, dlBimEtOBCOHlSHlHlHg one or there lesser number of teeth sny, for instance, the stationary 1 wheel or ra 'ek I, sixty-fourteeth, whilethe mova'hle wheel, J,1hassixty-three. Iri'geri r with this difl'erential arrengement'of wheels I and J, is a, pinion, K, arranged freely to rotate on or around a pin orstud, h, projecting from the handle G, so that on rotating the latter to work the drhwing and measuring-device G, the wheel J is moved. say, one tooth every time the pinion K travels ground the wheels I-iind J, whereby a simple and eflicientconnection is or may be estahlished with the indicator, capable of registering large quantities without a multiplicity of gearing.

To forin the connection with the indicating-dial P: Supposing the dial to more insteadof the pointer B,

said dial having, as is usual, suitable divisions marked on its face. The wheel J carries or is connected with a bevel-wheel, M, arranged to gear with a bevel-wheel or pinion, N, that operates 'asthe driver to the dial, and whereby a difierent velocity may be given to the latter, accordingly as the wheels M and N vary in diameter,

than that which is attainable from the wheel J direct. This difierence may be in favor either of an increased or reduced speed to the dial, but preferably the former, to. counteract in a measure the very slow movement of the wheel J relatively to the handle G or its shaft g, and measuring-device operated thereby.

The bevel-wheel or pinion N may be fitted to turn loosely on its shaft, m, that, being stationary, answers to carry the pointer R- and the dial P, also he made to turn freely round the some shaft with a spring,-s, or springs, interposed between it and thewheel N, and operating to press the dial'upor against an outside shoulder to the shaft, by which arrangement thedial, though driven, through frictional pressure of the spring by the wheel N, as required in the action of the indicator, is made capable, by turning it direct, of independent rotation, to vary its set or adjustmcnt'relotively to the pointer, accordingly as new or varied indications are required, and whereby the dial may rapidly be brought back to'its original position or set for a fresh measurement after a previous quantity has been run'ofi from the faucet, and this without disconnecting parts, or otherwise than applying the hand to the dial to turn it, and without breaking the gear of the latter with its driving-wheel, so thaton removing the'hand-fr om the dial after adjustment, it is in working connection with the gear operated by the measuring-device. p

' What is here claimed, and desired to be scouted by Letters Patent, is

1. The combination, with a rotary measuring and drawing-device, 0, arranged in the chamberB of the faucet A, and turned from the outside by crankorhandleG, of the fast and loose differential wheels I J, pinion K, carried by the handlennd'wheels M N, or their equivalents, for operating the dial P, substantially as shown and'desci'ibed. v

2. The dial P, hung for independent action, as described, and for free rotation with the wheel N, by which it is driven by frictional gear 'withthe latter, through a spring or springs interposed between said wheel and dial, essentially as specified. v
